Drug Testing Cutoff Levels at Jennifer Heidt blog

Drug Testing Cutoff Levels. These denote the concentration level of the drug metabolite. Cutoff levels are expressed in nanograms (ng) per milliliter (ml) for urine drug testing and oral fluid drug testing or picograms (pg) per milligram (mg) for hair drug testing. Drug tests target only specific drugs or drug classes above a predetermined cutoff level. It is important to select a specimen type and cutoff level based on the desired window of detection and any regulatory requirements. Cutoff levels are determined by (i) use case; For example, in workplace drug testing the federal cutoff level for a cannabis drug test in urine is. All positive results on immunoassays need confirmatory testing (eg, gas chromatography/mass spectrometry). § 26.163 cutoff levels for drugs and drug metabolites. 1 a cutoff level is a point of measurement at or above which a result is considered positive and below which a result is considered negative. Cutoff levels are expressed in nanograms (ng) per milliliter (ml) for urine and oral fluid testing or picograms (pg) per milligram (mg) for hair testing. Drug test cutoff levels are set measurement thresholds that determine if a test specimen is positive or negative for a specific controlled substance. For both screening and confirmation testing, there is an upper limit to the calibration range, above which drug levels cannot be determined with any accuracy. ( a ) initial drug testing.
